Decoding Stellar Population Properties of Dusty, IR-luminous Galaxies at 2 in CANDELS
Abstract
For a solid picture of galaxy evolution the robust determination of galaxy properties is crucial. A number of studies have used simulations to address this issue for the determination of stellar population parameters via SED-fitting for normal galaxies. In this work, we address the problem for IR-luminous galaxies at 2, whose properties might be more challenging to estimate due to their very high star formation rates and high dust content. We investigate Herschel detected sources in GOODS-S using CANDELS data via SED-fitting with a variety of reddening laws designed to reflect the spread of properties that has been observed for such sources in terms of their UV extinction (A_UV) versus reddening (UV spectral slope β). We will present comparisons for photometric redshifts, stellar masses, star formation rates, and other properties for the different parameter choices.
